neutroniaktivaatioon
Neutroniaktivaatio is a nuclear process and a fundamental analytical technique used to determine the elemental composition of a sample. It involves bombarding a sample with neutrons, typically from a neutron source such as a nuclear reactor or a neutron generator. When a nucleus within the sample captures a neutron, it becomes an isotope, often a radioactive one. This newly formed radioactive isotope is in an excited state and subsequently de-excites by emitting gamma rays or other particles.
The emitted gamma rays have specific energies that are characteristic of the particular isotope and, therefore,
Neutroniaktivaatio analysis is a non-destructive technique, meaning the sample can often be preserved after analysis, which
